KinoSearch::Search::IndexSearcher - Execute searches against a single index.
The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/
my $searcher = KinoSearch::Search::IndexSearcher->new( index => '/path/to/index' ); my $hits = $searcher->hits( query => 'foo bar', offset => 0, num_wanted => 100, );
Use the IndexSearcher class to perform search queries against an index. (For searching multiple indexes at once, see PolySearcher).
IndexSearchers operate against a single point-in-time view or Snapshot of the index. If an index is modified, a new IndexSearcher must be opened to access the changes.
my $searcher = KinoSearch::Search::IndexSearcher->new( index => '/path/to/index' );
index - Either a string filepath, a Folder, or an IndexReader.
Return a Hits object containing the top results.
query - Either a Query object or a query string.
offset - The number of most-relevant hits to discard, typically used when "paging" through hits N at a time. Setting
offsetto 20 and
num_wantedto 10 retrieves hits 21-30, assuming that 30 hits can be found.
num_wanted - The number of hits you would like to see after
offsetis taken into account.
sort_spec - A KinoSearch::Search::SortSpec, which will affect how results are ranked and returned.
Iterate over hits, feeding them into a Collector.
query - A Query.
collector - A Collector.
Return the maximum number of docs in the collection represented by the Searcher, which is also the highest possible internal doc id. Documents which have been marked as deleted but not yet purged are included in this count.
Return the number of documents which contain the term in the given field.
field - Field name.
term - The term to look up.
Retrieve a document. Throws an error if the doc id is out of range.
doc_id - A document id.
